String of hearts plant really does seem to be made up of dark green, silver, and purple hearts on a string. They are perfect for hanging baskets, or you can let them spread over a windowsill or a mantle piece.

A curious plant all around, the string of hearts bears long strings of heart-shaped, inch-long leaves, dark green with silver marbling above and a purple underside. Here and there along the stems are woody, pea-shaped tubers which, if put in contact with soil, will root and produce stems of their own, growing up to three inches in diameter.
The inch-long flowers, while not striking, are certainly odd-looking -- they resemble tiny purple lanterns.
